Let the nightmare begin. Novelist Ryu Murakami plans to release his latest novel exclusively for digital bookworms through Apple Inc.’s iPad ahead of the print version. Mr. Murakami, the acclaimed author of over 15 novels including “Coin Locker Babies” and “In the Miso Soup”, replaced the publishers with a software company to help develop the e-book titled “A Singing Whale,” or “Utau Kujira” in Japanese. The digital package will include video content and set to music composed by Academy Award winning composer Ryuichi Sakamoto, according to the Japanese business daily Nikkei.
